The invention provides an overwintering culture method of Danding peacock carp, which comprises the following steps: moving the fancy carp from the outdoor to the indoor, adding the heat preservation treatment liquid into the water pool at night, and stopping adding until the temperature of water in the water pool is 22-25 ℃; changing water once every 5-7 days, and adding a water quality improving agent into the water pool after the water is changed; putting the microbial compound preparation into water; after the mixture is moved indoors, the overwintering feed additive is added into the feed. The heat-preservation treatment liquid in the method increases the specific heat capacity of the water body and reduces the day and night temperature difference of the water body; the water quality regulator and the microorganism compound preparation are matched with each other to inhibit the breeding of pathogenic parasites in the water body; the overwintering feed additive enables the nutrient substances in the feed to be more comprehensive, increases the appetite of the feed, increases the growth speed of the feed in winter, improves the mental state, has more bright color and can improve the survival rate of the Danding-top brook carp in winter. |
